ENTOMOLOGICAL SECTION. 



Lepidoptera. — Mr. B. Morley writes : — After a long and 

 severe winter and a cold and wet April it soon became evident 

 that an extraordinary insect season was at hand, larvae began 

 to appear in great numbers on almost every kind of plant and 

 many species of lepidoptera have subsequently appeared in 

 the perfect stage in great numbers. 



The three species of White Butterflies have occurred in the 

 greatest abundance throughout the county. Vanessa uriiccB, 

 V. atalanta and V. io have been common in many places 

 during August and September. The reappearance of V. io 

 in numbers is noteworthy, as for many years this species has 

 been very scarce. Polyommatus phceas has also been abundant. 

 Argynnis aglaia is reported from Doncaster. Vanessa antiopa 

 was captured at Silsden on September loth, 1917, and another 

 seen at Wilsden during the same month. Many species of 

 moths have been very common ; the antler moth being perhaps 

 the most abundant, and the swarm not by any means confined 

 to the moors, this moth appearing during August in phenomenal 

 numbers in many low-land meadows. In June excessive 

 numbers of Scardia cloacella, Dasycera sulphur ella and Gly- 

 phipteryx fuscoviridella appeared in the West Riding ; the 

 same remark applies to the appearance of Penthina saiiciana 

 and Aphelia osseana on the moors in July, and to Gracilaria 

 syringella in the lowlands in August. 



Acherontia atropos is reported from Huddersfield and 

 Doncaster ; Sphinx convolvuli from Hebden Bridge, Keighley 

 (three specimens), Barnsley (two specimens), Middlesbrough 

 (seven), and Doncaster (common). 



Luperina nickerlii taken at Hebden Bridge in August, 

 has been brought to me, two larvae of Acronyda alni were taken 

 in Edlington Wood in the same month. 



Dr. Corbett reports Stigmonota nitidana and Choreufes 

 scintillulana common at Doncaster. 



Mr. T. Ashton Lofthouse reports from Middlesbrough 

 Penthina dimidiana plentiful, and from the same locality 



i^faturalisi,
